| 发明名称 | Detecting intentional corruption of data in a dispersed storage network | ||
| 摘要 | A method begins by a dispersed storage (DS) processing module of a DS unit selecting a data slice for corruption analysis and requesting integrity information for the data slice from one or more other DS units of a dispersed storage network. When the one or more requested integrity information is received, the method continues with the DS processing module analyzing the one or more received integrity information and local integrity information of the data slice stored in the DS unit. When the analysis of the one or more received integrity information and the local integrity information of the data slice is unfavorable, the method continues with the DS processing module identifying the data slice as being corrupted. | ||

| 主权项 | 1. A method for detecting intentional corruption of data in a dispersed storage network (DSN), the method comprises: selecting, by a dispersed storage (DS) unit of the DSN, a data slice for corruption analysis; requesting, by the DS unit, integrity information for the data slice from one or more other DS units of the DSN; when the one or more requested integrity information is received, analyzing, by the DS unit, the one or more received integrity information and local integrity information of the data slice stored in the DS unit; and when the analysis of the one or more received integrity information and the local integrity information of the data slice is unfavorable, identifying, by the DS unit, the data slice as being corrupted. | ||
